Innovations in Data Center Power and Cooling Solutions

Terra Innovatum, Uvation agree micro-modular nuclear pilot

Terra Innovatum Global, a developer of micro-modular nuclear reactors, and Uvation, an integrated technology provider, have signed a Letter of Intent (LOI) to launch a 1MWe pilot programme of Terra Innovatum’s micro-modular nuclear technology, with an option to scale up to 100MWe. The pilot is intended to support Uvation’s growing requirements for high-density AI and modular data centre infrastructure. Terra Innovatum develops micro-modular nuclear reactors, while Uvation focuses on technology platforms designed for large-scale, performance-intensive AI workloads. The companies state that behind-the-meter nuclear generation could provide a resilient and scalable alternative to grid-dependent power for data centre development. Alessandro Petruzzi, co-founder and CEO at Terra Innovatum, comments, “Uvation’s data centre expansion requires infrastructure that is not only scalable, but fundamentally resilient. "By integrating Terra Innovatum’s SOLO micro-modular reactor, we will offer a behind-the-meter energy source capable of delivering safe, stable, high-density power that traditional grids cannot guarantee. "SOLO adds built-in safety and provides redundancy - important for data centres, de-risking energy deployment during maintenance or shutdowns, ensuring continuity independent of power shortages, and enhancing cybersecurity protection. "This enables next-generation, high-performance modular data centres powered by a clean, uninterrupted energy backbone - unlocking new possibilities for AI, HPC, and mission-critical workloads.” Nuclear as an alternative pathway for energy-constrained AI projects Giordano Morichi, Founding Partner, Chief Business Development Officer and Investor Relations, adds, “As AI infrastructure outpaces today’s grid, the constraint is no longer processing power; it’s reliable, cost-effective power. Uvation’s future commitment to behind-the-meter nuclear reflects a broader market reality: energy security now defines the speed at which AI can scale. "SOLO fast-tracks AI commercialisation by providing near-instant, CO₂-free, revenue-generating power while sidestepping the delays and CapEx overruns inherent to traditional grid-dependent solutions. "This agreement also strengthens our commercial deployment and positions nuclear as the most viable path to support Uvation’s planned multi-gigawatt growth in the AI and data centre sector.” Reen Singh, CEO of Uvation, notes, “Global demand for AI, driven by the US, and the need for sovereign cloud infrastructure is accelerating far faster than the available power to support it. Some of our off-takers forecast demand exceeding 1GW, yet current infrastructure and lack of readily available access to energy limit the scale of deployments. “Power shortages have been major forces in this industry’s project delays. By integrating Terra Innovatum’s SOLO reactor into our future roadmap, we will look to secure immediate power along with a reliable, behind-the-meter energy source that enables scalable AI, inference, and edge deployments. "Our future 1MWe SOLO pilot program represents a critical first step, with a path to expand to 100 MWe across multiple sites and potentially several megawatt-scale installations throughout the US.” The companies intend the pilot to act as a foundation for potential multi-site expansion, citing accelerating power demand and increasing constraints on conventional grid-connected data centre projects.

NorthC, Legrand upgrade Münchenstein (Basel) data centre

NorthC Data Centers, a Dutch provider of sustainable data centre and colocation services, has partnered with Legrand, a French multinational manufacturer of electrical and digital building infrastructure products, to upgrade its Münchenstein (Basel) site, introducing higher-density infrastructure to support AI, hybrid-cloud, and high-performance computing workloads. The project was completed within a six-month window to meet rising regional demand for GPU-driven environments. NorthC operates regional facilities across Switzerland, the Netherlands, and Germany. The company sought to replace low-density systems and traditional air-cooling at the Münchenstein site to accommodate higher power and thermal loads associated with modern AI deployments. Legrand, through USystems, supplied rear-door heat exchangers for rack-level cooling. These units are mounted to the rear of server racks, absorbing heat from server exhaust and transferring it through a heat exchanger before returning cooled air to the data hall. The closed-loop design supports higher rack densities while improving energy performance. The cooling equipment was installed while the data centre remained live, a process described by Wolfgang Voigt, Münchenstein Data Center Site Manager at NorthC, as “like open-heart surgery.” Focus on efficiency and future expansion NorthC reports that energy consumption at the site has fallen by about 80% following the cooling upgrade and broader infrastructure improvements. The facility now supports GPU-based clusters, hybrid-cloud environments, and high-density workloads, while maintaining compliance with Swiss data protection requirements. Wolfgang says, “Adopting the energy-efficient RDHx technology has been a game-changer for us. The fact that it enables high-density computing while reducing energy consumption makes it a compelling choice to meet AI and HPC requirements.” The upgraded design also accommodates future development, including additional rack capacity or a shift towards liquid or direct-to-chip cooling. NorthC says it continues to pursue its long-term sustainability goals through efficiency measures and ongoing optimisation of existing sites. Colin Rowlands, European Technical Support at USystems, notes, “Installing the basic infrastructure for our cooling solutions in a data centre, whether in the entire data centre or just part of it, makes upgrading easy. "The joint solution, which we are very proud of, provides NorthC with future-proof and flexible infrastructure.” For more from NorthC, click here.

Why cooling design is critical to the cloud

In this article for DCNN, Ross Waite, Export Sales Manager at Balmoral Tanks, examines how design decisions today will shape sustainable and resilient cooling infrastructure for decades to come: Running hot and running dry? Driven by the surge in AI and cloud computing, new data centres are appearing at pace across Europe, North America, and beyond. Much of the debate has focused on how we power sites, yet there is another side to the story, one that determines whether those billions invested in servers actually deliver: cooling. Servers run hot, 24/7, and without reliable water systems to manage that heat, even the best-connected facilities cannot operate as intended. In fact, cooling is fast becoming the next frontier in data centre design and the decisions made today will echo for decades. A growing thirst Data centres are rapidly emerging as one of the most significant commercial water consumers worldwide. Current global estimates suggest that facilities already use over 560 billion litres of water annually, with that figure set to more than double to 1,200 billion litres by 2030 as AI workloads intensify. The numbers at an individual site are equally stark. A single 100 MW hyperscale centre can use up to 2.5 billion litres per year - enough to supply a city of 80,000 people. Google has reported daily use of more than 2.1 million litres at some sites, while Microsoft’s 2023 global consumption rose 34% year-on-year to reach 6.4 million cubic metres. Meta reported 95% of its 2023 water use - some 3.1 billion litres - came from data centres. The majority of this is consumed in evaporative cooling systems, where 80% of drawn water is lost to evaporation and just 20% returns for treatment. While some operators are trialling reclaimed or non-potable sources, these currently make up less than 5% of total supply. The headline numbers can sound bleak, but water use is not inherently unsustainable. Increasingly, facilities are moving towards closed-loop cooling systems that recycle water for six to eight months at a time, reducing continuous draw from mains supply. These systems require bulk storage capacity, both for the initial fill and for holding treated water ready for reuse. Designing resilience into water systems This is where design choices made early in a project pay dividends. Consultants working on new builds are specifying not only the volume of water storage or the type of system that should be used but also the standards to which they are built. Tanks that support fire suppression, potable water, and process cooling need to meet stringent criteria, often set by insurers as well as regulators. Selecting materials and coatings that deliver 30-50 years of service life can prevent expensive retrofits and reassure both clients and communities that these systems are designed to last. Smart water management, in other words, begins not onsite, but on the drawing board. For consultants who are designing the build specifications for data centres, water is more than a technical input; it is a reputational risk. Once a specification is signed off and issued to tender, it is rarely altered. Getting it right first time is essential. That means selecting partners who can provide not just tanks, but expertise: helping ensure that water systems meet performance, safety, and sustainability criteria across decades of operation. The payback is twofold. First, consultants safeguard their client’s investment by embedding resilience from the start. Second, they position themselves as trusted advisors in one of the most scrutinised aspects of data centre development. In a sector where projects often run to tens or hundreds of millions of pounds, this credibility matters. Power may dominate the headlines, but cooling - and by extension water - is the silent foundation of the digital economy. Without it, AI models do not train, cloud services do not scale, and data stops flowing. The future of data centres will be judged not only on how much power they consume, but on how intelligently they use water - and that judgement begins with design. If data centres are the beating heart of the modern economy, then water is the life force that keeps them alive. Cooling the cloud is not an afterthought; it is the future.

ABB supplies power tech for Applied Digital's AI factory

BAC releases upgraded immersion cooling tanks

Baltimore Aircoil Company (BAC), a provider of data centre cooling equipment, has introduced an updated immersion cooling tank for high-performance data centres, incorporating its CorTex technology to improve reliability, efficiency, and support for high-density computing environments. The company says the latest tank has been engineered to provide consistent performance with minimal maintenance, noting its sealed design has no penetrations below the fluid level, helping maintain fluid integrity and reduce leakage risks. Dual pumps are included for redundancy and the filter-free configuration removes the need for routine filter replacement. Design improvements for reliability and ease of operation The tanks are available in four sizes - 16RU, 32RU, 38RU, and 48RU - allowing operators to accommodate a range of immersion-ready servers. Air-cooled servers can also be adapted for immersion use. Each unit supports server widths of 19 and 21 inches (~48 cm and ~53 cm) and depths up to 1,200 mm, enabling higher rack densities within a smaller footprint than traditional air-cooled systems. BAC states that the design can support power usage effectiveness levels of up to 1.05, depending on the wider installation. The system uses dielectric fluid to transfer heat from servers to the internal heat exchanger, while external circuits can run on water or water-glycol mixtures. Cable entry points, the lid, and heat-exchanger connections are fluid-tight to help prevent contamination. The immersion tank forms the indoor component of BAC’s Cobalt system, which combines indoor and outdoor cooling technologies for high-density computing. The system can be paired with BAC’s evaporative, hybrid, adiabatic, or dry outdoor equipment to create a complete cooling configuration for data centres managing higher-powered servers and AI-driven workloads.
